Packing Tape Slitting Machine

Packing Tape Slitting Machine

Introduction to slitting machine:
     Slitting machine is a kind of mechanical equipment for slitting wide sheets of paper or film into a plurality of narrow-width materials, which are commonly used in papermaking machinery and printing and packaging machinery.
     The traditional control scheme of the slitter is to use a large motor to drive the shaft of the rewinding and unwinding. A magnetic powder clutch is added to the reel and reel, and the resistance generated by the magnetic clutch is controlled to control the tension of the surface of the material. . Magnetic powder clutches and brakes are special automatic actuators that transmit torque through the magnetic powder filled in the working gap. The magnetic current can be changed to change the magnetic state of the magnetic powder, and then the transmitted torque can be adjusted. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high speed section fine adjustment and medium and small power speed control system. It is also used to adjust the torque by adjusting the current to ensure an unwinding or rewinding tension control system with a constant tension during winding.

Eight. Indentation
There are two reasons for the cause of film roll indentation. One is caused by the winding wheel of the film forming process, and the other is caused by the cutting factor. The reasons for the cutting are:
1 Due to the poor adjustment of the angle of the puller wheel, the pressure and tension of the puller wheel are concentrated on one point of the film, and the friction of the contact point causes damage to the film surface to form an indentation.
2 The winding roller is damaged, such as scratches, etc., the degree of film roll indentation is large when the scratch is longitudinal; 3 The winding roller is contaminated, causing the surface of the pressure roller to be uneven, such as adhesive tape, impurities, etc. It will also cause the film roll to be indented and the press roll must be cleaned.
Slight indentation does not affect the use of the product, but it affects the appearance of the product, causing the customer to doubt the quality of the product; the obvious indentation not only affects the appearance of the product, but also attenuates the corona value of the film, affecting the film. Processing performance.

nine. Scratch
      Whether the slitting and scratching can be compared and determined by the film surface before and after the slitting, there are various reasons for the scratching of the membrane surface, and the analysis should be based on the appearance of the scratch, such as short-line scratching. The difference of the speed ratio of each drive roller exceeds the process setting requirement, and it needs to be carefully tested and adjusted. If the film surface scratch occurs continuously, the film on the slitter should be inspected for whether it touches the fixed object or cuts each. Whether the roller adheres to dirt such as fine sand grains scratches the film surface.
Scratch is the appearance quality problem of the film, which directly affects the quality appearance of the deep-processed product. Therefore, it is not allowed to exist in the film quality control standard. The slitting process finds that the scratching problem must be carefully checked and quickly eliminated. Since the scratch on the film surface is an irreversible appearance quality problem, it is not allowed to operate the disease when the film surface is scratched, so as to avoid the continuous occurrence of the problem.
